STAPLE-STRI-P BLANK.

SPECIFICATION forming part of Letters Patent No. 358,985, dated March 8,1887.

Application tiled November l, 1886. Serial No. 217,663. `(No model.)

To @ZZ whom, may concern;

Be it known that I, FREEBORN F. RAY- MOND, 2d, ofNewton, in the countyofMiddlesex and State ot' Massachusetts, a citizen of the United States,have invented a new and useful Improvement in Strips for Forming Staplesor Two-Pronged Fastenings, of which the following is full, clear, andexact description, reference being had tothe accompanying drawings.forming a part ot this specification, in explaining its nature.

The object of the invention is to provide a strip or blank from whichtwo-prong fasten ings or strips may be cut, which shall have eccentricpoints and long bevels formed upon the same side of each shank or prongot' the staple or fastening.

In the drawings, Figurel is a View in elevation ofthe blank strip. Fig.2 is a vertical section upon the dotted line of Fig. l. Fig. 3 is a viewin perspective otthc complete staple or two-prong fastening. Fig. et isa view in side and end elevation of a plate from which the strip isformed. Fig. 5 is a View in side and end elevation ot" a plate ofsomewhat different shape from that shown in Fig. 4. Fig. 6 is a view insection illustrating a staple formed from said strip. t

The blank strip is cut from a plate of metal of uniform thicknessthroughout, (see Fig. 4,) or from a plate having the inclined ortapering surface, as represented in Fig. 5, and so as to form a seriesof shanks or prongs, a, connected at their upper ends by an uncutsection` a', ofthe plate.

Vhen the plate is formed as represented in Fig. 5, it will provide thelowerendsof the shank with the eccentric points and long bevels a3.W'hen the plate used in Fig. 4 is employed, the blank strips aresubmitted to a further forming operation, whereby the lower ends oftheshanks are ilattencd sufticiently to forni the long bevel a and theeccentric point a2. rPhe staple or two prong fasteningis completed byseparating the strip upon the lines b. The object in thus shaping theShanks or prongs is to provide astaple or fastening that shall indriving be compelled, because of the shape ofits point, to take aninclined course rather than a straight course.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States--- A staple or two-prong-tstcningstrip blank comprising a continuons head or section having a series ofdepending shanks or prongs, a, having the long beveled or inclinedsurfaces ce, andthe eccentric points ai, substantially as described.
